Dominica Wong’s work has been highlighted in a PNAS Commentary by Liangbing Hu and Kang Xu from the University of Maryland and the U.S. Army Research Laboratory respectively. The piece focuses on Wong’s research on the use of perfluoropolyethers (PFPEs) as electrolytes for lithium ion batteries. Noting that the research is an encouraging advance toward a safer lithium ion battery, the authors also suggest that the work could have benefits “beyond lithium ion” battery chemistry as well.
